Title: Testing circuit of thyristor characteristic
Inventor: HASHIZUME KEN
IPC: G01R31/26
Filed: 1982-03-18
Abstract: PURPOSE:To measure the dv/dt dielectric strength of a thyristor to be tested accurately, by finding a lamp rate corresponding to a current of an electric current source right before the thyristor to be tested turns on form actual function relation. CONSTITUTION:A relay contact 21 is broken firstly and the function relation between the current I of a current source 10 and the lamp rate R is found. Then while the value of the current I is varied, the lamp rate R is found repeatedly to an adequate frequency to find the function relation between the current I and lamp rate R. Thus, in the stage where the actual function relation between the current I and lamp rate R is found by repeating lamp voltage generating operation, whether a testing circuit operates normally or not is found and while the current I is increased gradually, the lamp voltage generating operation is repeated until the thyristor 13 turns on. Consequently, the lamp rate R corresponding to the current I right before the thyristor 13 turns on, i.e. the dielectric strength dv/dt of the thyristor is found from said actual function relation.

Title: Production for semispherical side wall of vertically split spherical tank
Inventor: SATAKE RIYOUZOU
IPC: B29C70/30
Filed: 1981-03-24
Abstract: PURPOSE: To produce semispherical side walls enhanced in stiffness and strength without generating any gaps or displacement by a method wherein an annular jig member capable of maintaining a curved shape of a heat-insulating strip against the recoiling force of the strip is fixed to the peripheral surface of an end of an FRP outside surface layer.  
     CONSTITUTION: The FRP outside surface layer 1 is formed by a hand lay-up method through a mold release agent coated on the inside surface thereof, and after solidifying the FRP layer 1, the annular jig member 4 made of the same material as that of the warming strips 2a is fixed to the peripheral surface of the end part of the layer 1. A plurality of heat-insulating strips 2a having elastic property and the same shape are attached to the entire inside surface of the FRP layer 1, that is, in a semispherical shape, with an FRP intermediate layer or adhesive 5 therebetween. In this case, since each of the strips 2a is curved against the elastic force thereof and is adhered to the adhesive 5, a recoiling force is generated and is concentrated at the opened part of a mold A. However, the heat-insulating strips 2a is prevented from displacement by the annular jig member 4.

Title: Viterbi decoder
Inventor: ITAKURA EIZABURO
IPC: H03M13/41
Filed: 1993-03-04
Abstract: PURPOSE:To shorten the pull-in time by using a conflict counter as a synchronism protection circuit and combining an asynchronous counter with the conflict counter to count the asynchronously decoding time after a synchronism pattern is changed. CONSTITUTION:A viterbi decoding part 1 supplies the synchronism information to a synchronism detecting part 2, and the part 2 outputs a synchronism detecting signal to a counter control part 3 based on the synchronism information. A synchronism protection circuit of a conflict counter system consists of a front counter 6 and a rear counter 5. When the circuit state is temporarily deteriorated, an error is increased and the synchronism detecting signal shows an asynchronous state. Under such conditions, the counter 6 is counted by one. If no error is detected, the counter 5 is counted up. A complete pull-out state is decided when the asynchronous state of the synchronism detecting signal continues by five times. Thus an asynchronism counter 4 is actuated to output a synchronism control signal to a synchronism control part for switching a synchronism pattern.

Title: Power supply equipment, discharge lamp lighting equipment, and luminaire
Inventor: ASAMI KENICHI
IPC: H05B41/24
Filed: 1996-02-29
Abstract: PROBLEM TO BE SOLVED: To eliminate danger of breakdown of a switching transistor, and increase high frequency output of a power supply. SOLUTION: When a power supply is turned on, a charging current of a capacitor 3 flows in the gate of a transistor Tr2 through a trigger diode TD, and the transistor Tr2 is started, so that transistors Tr1, Tr2 perform switching. In this case, a voltage, e.g. generated on the secondary side Bch 21 of a ballast choke Bch is applied to the gate of the transistor Tr1, through an integrating circuit constituted of a resistor R3 and a capacitor C4. Since the voltage generated on the Bch 21 of the secondary side passes the integrating circuit, the waveform width is increased and the period is decreased. Therefore, the switching frequency is decreased and high frequency power to be supplied to a discharge lamp 4 is increased.  The secondary side winding of the ballast choke Bch is not wound up, so that the voltage applied to the gate does not exceed the rating of the transistor Tr1 and it is broken down.

Abstract: PURPOSE:To improve the yield of a product by changing a pass schedule from a preceeding material to a succeeding material so that the temperature of an extruded material on the outlet side of a mill at the time of flying change approximates to a target value. CONSTITUTION:In flying changing rolling of a hot finishing mill consisting of 1st-5th stands 1-5, a tracking part 25 calculates the position of the flying changing part to give a positional signal to a roll speed setting part 24. On one hand, when the flying changing part comes near the inlet side of the mill, a data inputting part 22 gives a data required by a finish rolling to a setting calculation part 23. The setting calculation part 23 calculates a roll gap and a speed set value of each stand to the succeeding material through information regarding this succeeding material, further, a deviation from the temperature and the target temperature on the outlet side of a finish mill is calculated and this deviation decides the minimum roll speed changing method and is informed to a roll speed setting part 24. This setting part 24 decides a roll speed changing timing of each stand and changes the roll speed set value. In this way, the pass schedule from preceeding material to the succeeding material can be changed.

Abstract: PURPOSE:To ensure a high-speed and stable operation of a logical circuit, by providing a discharging means for discharging the electric charge at the joint of a logic setting part and a precharging MOSFET. CONSTITUTION:A discharging MOSFETT5 is provided between a joint A of a logic setting part 11 and a precharging MOSFETT1 and a joint C of the part 11 and a discharging MOSFETT2. Electric conduction is controlled by the potential of an output signal OUT for the MOSFETT5. When a synchronizing signal phi' is set at 0, FETT1 and T2 are turned on and off, respectively. Then the  joint A is set at 1. As a result, the output signal of an inverter circuit is set at  0. Then the signal phi' is set at 1, and therefore the level of the joint A is set at  0 as long as the logic of the part 11 is satisfied. Thus the signal phi' is set at 1,  and therefore FETT1 and T2 are turned off and on, respectively. As a result,  the electric charge of the joint A is quickly discharged via FETT5 and T2.
